5.9.4.1 Regulator Assembly

1. Using a 3mm hex key, remove the 4 screws that secure the valve housing bottom cover and remove the
cover.
2. Disconnect the tubing from the straight push-in fitting on the regulator assembly.
3. Using two adjustable wrenches, turn the 14mm hex nut on the inside of the housing while holding the hex
on the regulator on the outside of the housing to loosen the assembly. Remove the regulator assembly.
4. To replace the regulator inlet filter, use a wrench to remove the elbow fitting, then turn the filter fitting off
the regulator. Before installing a new filter, make sure all old PTFE tape remnants are removed and new
tape is applied.
5. When installing the new regulator assembly, be sure to replace the M14 lock washer under the 14mm hex
nut. Hold the regulator so that when it is installed the oxygen supply fitting points straight down at the floor.
Perform the Pre-use Checkout.
